MATRIX-HOLDER FOR TYPE-CASTING MACHINES.

Specification of Letter-is` Patent. i Patented June 24, 1919,

Application led October 20, 1917. Serial No. 197,656. I

To all whom t may concern:

\ Be it known that I, FRANK` HINMAN PIERPONT, a citizen of the United States, residing at Horley, county of Surrey, England, have invented certain new and useful Improvements in Matrix-llolders for Type- Casting Machines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the characters of reference marked thereon. c

This invention relates to matrix holders for type casting machines of the class illus trated in Letters Patent No. 625,998, dated `May 30th, 1899 and wellknown commercially as manufactured by Lanston Monotype Machine Company, and refers'particularlyto holders for display-type matrices to be employed in connection with suchtype casting machines to enable them to be used for display-type casting.

Display-type are, as a rule, of greater dimensions than type designed tobe used in the production of composition or composed matter, `or they are of a character which it is not desirable to produce from the regularmatrix equipment provided for normal composition, because of the infrequency with which the charactersare used, and hence it becomes desirable to provide the machine with means whereby the display type matrix holder may be quickly and conveniently substituted for the regular matrix holder or die case and with means whereby the display matrices themselves may be easily ,and mconveniently changed so as to give a maximum capacity with a minimum labor on the part of the attendant.

The tvpe matrix employed in the production of display tvpe and designed to be held c in the devices Jforming the subject matter c, c

1 jaw 9, `the plungerbeing guided in a hollow I rib 10 and being directly acted upon by a spring, 11; and a lever 12, pivoted to the of the present invention is well lnown, bein illustrated, for example, 1n Letters Patent 904,510 dated Novemberj24th, 1908;

in this patent there isalso shown a matrix holder ofthe general kind to which the presc adapted being clearly set forth insaid Letters Patent `:,t:625,996 above referred to; and

the objects of the invention are generally to provide a matrix holder in which a plurality of matrix clamping members directly engagewitn the matrix each being independently spring-controlled, a holder` equipped with temperature controlling means and hav- `ing means whereby the position of the matrix contained in theholder may be varied .with respect tof themold in connection with which the matrix is used.

`Referring tothe accompanying drawings throughout which similar parts are indicated bythe same reference characters,

Figure l1 is a bottom plan view of a matrix "holder, embodying the present invention; I i

r n Fig. 2 is a sectional view, the section being u taken substantially on` the line 2-2 of 1.V l `1 Fig. 3 is a top plan view and Fig. 4 is a section, somewhat enlarged,

l substantially on the line 4:-4 of Fig. 3.

The body portion or frame l is proi vided with side ribs 2 and 3 to permit the holder to be substituted for the usual matrix holder of the casting machine. The frame l1 is provided on its `under face with two c `stationary gaging projections4 and "5 at right angles to each other. The matrix A which is of rectangular `form has two gagfing edges Ll` `and 5 formed on sides at right angles to each other and adapted to bear against the gaging projections 4 and 5 respectively; the matrix A is also provided with two clamping edges 6 and 7 preferably beveled 1and ocated at diagonally oppositecorners ofthe matrix,` these edges cooperating with spring controlled clamping devices. The latter consist of a plunger 8 provided with a matrix engaging clamping handle 15, a spring 16, acting directly upon the lever 12. The spring 11 is held by the ,y

screw 16 so as yieldably to maintain the" jaw 9 ofthe plunger 8 in advanced or ;clampingposition. The plunger 8 is also provided with a projection 17 (see Fig. 3)

which` is s guided bythe walls of the slot 18 in the matrix holder Liframe, such arrangement being provided to prevent the turning of the plunger in its guiding rib 10 and to assure or the correct position Yof the clamping jaw 9.

The spring 16 isgheld by the screw 159 so as to exert pressure on the bolt 20 guided in the lframe rib 21 and engaging at its Outer endvvith the vlug 22 of the lever, Ythus tending yieldably to maintain the lever with its clamping javv 14 in advanced or matrix i 'clampingpostion The spring 1'6 Aext-,rtg a l-greater pressure than the 'spring 11, 'the main purpose Eof the llatter and the cl-amping jaw Jv9 seing 'to hold 'the matrix A te its 'seat 'and allovv lor -`c'ompens`ate for any 'slight 'irregularity 1in the construction of 'the body 'of the matrix.

The guiding "extension 23 'of the frame 1 visprovide'd vvith a stop or projection 524 for 'engagement lwith the lever handle I15 vt'ohold 'sa-id lever lwith its javv in retracted position.

To place a matrix upon lits seat or remove it therefrom, the handle 15 is moved to 'turn th'e lever on its pivot 13 and draw the clamping 'ifav '(314 to its retracted position. In this rmotion 'of the handle it is sprung over the "stop 424 and be positioned beh-ind the stop, asshovvn in dotted lines in Fi-'g. 1',`t0 maintain the jaw rr in retracted position. When matrix has been platee en the triX seat in :approximately correct position, the handle is released 1fro'mthe stop -alld by ineans'of the 'spring 16 the lever 12 is caused to take rup the 'pera-uve position shown in ulfl'lines in Fig. l. Tn 'assuming this po- "sitio'nfth'ey maitrix is'inovedagainst the Wea-lier spring 'il enti-1 its Sturm-sa and 5 have seated against the lgage sufrffaces 4 fand 5 respectively. 'The clf'ainpingjaws 59 14 are .preferably `undereutand engage with beveled portions 6" and 7 of the inatrixa v'The frame its provided nath a cavity 25 in communication with which 'are 'the rib channels '26 which terminatte o'neon each fside of 'the holder hand-le f2?. 'The cavity 'may conveniently be l formed :by covering' a fc'ast or bored recess bya plate f2s pressed or ther- `Wisesecured Ain place lin such nianner *to "prevent leakage. The 'cavity 'in proximity to the matrix vseal; e9 and the -ten'lperature or 'the matrix is adapted "to be controlled by circulating 'a' temperature 'controlling "iluid, Snell 'as water, through the channels 26 and cavity e5. The Outside-@nus for thelchannels 26 may be connected by a flexible tube "26 or the like "with a source of'such fluid. The

, mold lWater cooling channels may, if desired,

ybe thus placed in 'co'mn'innic'ation Withthe ',cavity v`E25, in which ,'c'ase 'the temperature of the matrix ,A may 'be vri,un"ainta'ined l"at about "the 'san-ie temperature as y'the nold.

The maar is pastiglie-d accurate-1y with .rresp'ectto the mold of the casting machine 'by' ure tne-hole '3o inthe herder-into which cone-hole the centering pin of the casting machine is adapted to enter, as will be readily understood by those skilled in the art. llt is at times necessary to vary the position of matrices as When their character depressionsare differently located lwith respect to their gage surfaces 4', 5 or When a mold of .point size diierent from the point size of the matrix is employed. According to the present invention this is accomplished by 75 placing the cone-hole 30 in a movable plate 81. This plate is slidably lmounted on the frame 1 and is provided With a series of apertures each of which may by sliding the plate 'be aline'd with a corresponding ap- 80 ertnre 3,3 in the trame. When tivo corresponding apertures are alined, a positioning 'Spin `or doivel 34 is screwed into the plate aperture, which is screw-threaded for the purpose, the shank of the pin extending into the frameaperture so as to prevent further slidi-nfg rmotion ot the plate. When a pair of these apertures are alined no other pair is in alfin'ement ybut anew adjustment olthe plate is *required to 'bring about such a condition. 90 In zthis ivay the platemay be made to take up a variety 'off positions each ott which is fixed and definite and ieach "of which adjusts the 'done-hole accurately for the particular nol'd 'and matrix used. rIhe 'construction is 95 ysuch that a fine *adjustment may 'be secured 'with the use of relatively large holes 'and a large and strong pin. When the positioning `pin has bee1i=screvveclinto place 'the `fastening screw '35, its fs'ha'nk screw-'threaded into an 100 aperture in the l'rafnle and 'extending through afslo't in the plate 311 and its 'head adapted to contact *with the *top Walls 'of the plate lsurroundir'ig the slot, is 'screwed down to fassis't 'in maintaining immovable the estab- 105 lished frelation tbetween the plate and the traine.
